I was anorexic beforehand so I gained normal weight back due to appetite increase. I was on an insanely strong hormonal birth control that commonly causes weight gain of about 50 lbs, then Put on tons of medications for a genetic blood vessel disorder, 2 autoimmune disorders, and various other things. Ive been to over 15 doctors in the past year, all of which said that my medication cannot be changed and to eat better to improve weight loss, sent to a nutritionist who had me track calories which avg'd to 1100 a day, my doctors said if i ate less I wouldn't be able to work anymore. I have lost about 25 lbs since all the gain in the past few months but only due to tremendous stress causing me to not eat for days at a time. I am at a healthy weight but only because of an eating disorder.
